🏆 Wabash Valley — Managed wetlands and forest in the Wabash River valley — where Illinois meets Indiana
Marshall State Fish & Wildlife Area protects wetlands and forest in Clark County along the Wabash River valley — the historic border between Illinois and Indiana. The Wabash was one of the great rivers of the frontier era, immortalized in the state song of Indiana (“On the Banks of the Wabash, Far Away”). George Rogers Clark captured the British Fort Sackville at Vincennes (just across the river) in 1779 — one of the decisive campaigns of the American Revolution in the west.

Insider Tips
Wetland management: Marshall FWA manages bottomland forest and wetland habitat along the Illinois River — critical waterfowl staging habitat.

Duck hunting: Marshall is one of central Illinois’s premier public duck hunting areas — the Illinois River flyway is legendary.
Best Time to Visit
Fall: Waterfowl migration and duck season. Spring: Shorebird migration on mudflats. Summer: Fishing and birding. Winter: Eagle watching.
Frequently Asked Questions
Why is the Illinois River important for waterfowl?
The Illinois River valley is one of the most important waterfowl corridors in North America — millions of ducks and geese funnel through each fall. The river’s extensive bottomland wetlands provide food and resting habitat. Illinois historically harvested more ducks than any other state east of the Mississippi.
Wildlife & Nature
Marshall State Fish and Wildlife Area in Clark County provides managed recreation in the Wabash River lowlands of eastern Illinois. The Wabash — forming 200 miles of the Illinois-Indiana border — is one of the longest free-flowing rivers in the eastern United States. The river’s floodplain forests and wetlands support diverse fish and wildlife communities. Channel catfish, flathead catfish, and smallmouth bass inhabit the river. Wood ducks — arguably North America’s most beautiful duck with their iridescent green, purple, and chestnut plumage — nest in tree cavities along the river. White-tailed deer are managed through seasonal hunting. Eastern wild turkeys — whose restoration is one of wildlife management’s greatest success stories — gobble from the forest ridges in spring.
